I agree with Martin. I would also pot in something conducive to the size/shape, leaving buds above surface, and watch.
From experience, I can tell you that some cuttings will bud and leaf without roots, some will root vigorously and not bud for many weeks after, and some will root and bud at the same time. If you are seeing roots, chances are you will eventually see buds.
I wait until the roots are well-developed, showing on all sides of cup and circling the bottom) before moving to larger pot with no clear sides and moving towards a light source. I don't know what the more advanced experts recommend, this is just what I've been doing because it is working... =)
